Cross-Layer Reliability Modeling and Optimization: Compiler and Run-Time System Interactions

This paper presents a cross-layer reliability modeling and optimization approach that leverages multiple software layers like compiler and run-time system to improve the overall reliability considering unreliable or partially-reliable hardware. In order to bridge the gap between hardware and software to achieve high efficiency, our technique incorporates the knowledge from hardware layers during reliability modeling and design of optimization techniques. We demonstrate how different software layers operate synergistically to achieve a high degree of reliability.
